VENTILATOR Filed Oct. 3l. 1929 Patented ec. 9, 1930 UNITED STATES PATENT OFFICE HERMAN G. HUEGIQIN, 0F CHICAGO, ILLINOIS, ASSIGNOB T0 FEDERAL HEBGHNDIS C0., OF CHICAGO, ILLINOIS, A COEPOBATIQN OF ILLINOIS VENTILATOB This invention relates to ventilators, more particularly to an impro Jed panel construcfA tion for mounting a ventilator of the exhaust type in the window of a room.

In my copending application, Serial No. 380,003 filed July 2,2, 1929, I disclosed a ventilating panel in which an electric fan is centrally mounted in a framework by the mounting ring of the fan itself.

The space around the mounting ring of the fan and inside of the border line of the framework is lled in with a panel which preferably is constructed of glass so that the v installation of the device in the window of a room does not materially darken the room.

In my present invention, I provide a new and improved panel structure of this type, the improvement making the panel cheaper to manufacture, and at the same time adding 2@ beauty and grace to its appearance.

Now to acquaint those skilled in the art with the teachings of my invention, reference is here made to the accompanying drawings in which a preferred` embodiment of it is shown by way of example, and in which:

Figure 1 is an elevational View of a completely assembled panel;

Figure 2 is a cross-sectional view taken in a horizontal plane through the improved panel so showing it mounted in a window;

Figure 3 is a perspective view of the mountin bracket;

Figure 4 is a sectional view taken along the line 4-4 of Figure 1; and

Figure 5 is a cross-sectionaly view taken along the line 5--5 of Figure l.

The improved Ventilating panel made in.

accordance with the teachings of the present invention like its predecessor disclosed in my above mentioned copending application, is adapted to be mounted in the upper part of a window by the brackets 1 which are substantially L-shaped brackets having depending flanges 2 and 3 which fit over the top and bottom edges of the panel respectively. The mounting side of the bracket 4 is provided with slots 5 and 6 through which thumb screws 7 are projected and threaded into the mounting plate 8 which is rigidly attached to the Window frame. By this arrangement,

Application mea caterer s1, ieee. smal, No. 408,106.

the panel can be moved at right angles to the plane of the window sash so that the sashes may be operated to their fullest extent when it is desired to clean the windows, or if desired the Ventilating panel can be moved into the path of the upper sash 9 as it is shown in Figure 2.

The details of this mounting arrangement are fully covered in my above mentioned copending application, to which application reference is here made for those details.

In my present invention, the fan 10 is provided with the customary mounting rings 11 and 12 by which it is mounted in the panel structure. A particular type of fan is not of the essence ofthe present invention as any suitable type electric fan can be used in the panel of my invention.

The panel upon which the fan is mounted and supported in the window of a residence, comprises the side rails 13 and 14 which are of U-shape cross-section as will best be seen in Figures 4 and 5. These side rails may be constructed of brass, aluminum, or any other preferred metal, and are cut to such a length that they extend fully across the top and bottom sides respectively of the panel structure.

The panel members 15 and 16 are disposed upon opposite sides of the mounting rings 11 and 12 of the fan and held in place by their engagement with the panel members 13 and 14. In the preferred embodiment of 'my invention the panel members 15 and 16 the spacing strips 17 and 18. If the panel 16 is constructed of glass, it is preferable that the spacing members 17 and 18 be soft materials such as felt, cork, or the like, so that they cushion the panel in the side rail and prevent breakage-of it due to the unequal expansion' of the metallic side rail'and glass panel responsive to temperature variations.

' In constructing the preferred embodiment of my invention, the interior dimensionv of the s1de members 19 and 2O of the rails 13 and 14 is such that they have to be pressed onto the s acers 1 and 18, and this press tit is rehed upon for holding the panel members in the frame.

In order ltoeliminate the necessity of supporting the electric fan upon the glass panel members 15 and 16 I have provided mounting plates 21 and 22 which are pressed into the side rails 13 and 14 respectively at .the midpoint of those rails. The mounting plates 21 and 22 are constructed of metal, which may be brass, aluminum or any other preferred metal, of such thickness as to form a press fit with the interior surfaces of the walls 19 and 20 of the-rails 13 and 14. To

- securelymount the mounting plates 21 and 22 in these rails andto guard against the possibility of their being shaken loose by the vibration of the fan, I have provided rivets 23 which are projected through the sides 19 and 20 of the rails and the mounting plates 21 and 22 to hold those plates in their respective rails.

It will be apparentl that the thickness of the mounting plates 21 and 22 must be equal to the thickness' of the panels 15 and 16 lus two thicknesses of the spacing mem ers 17 and two thicknesses of the spacing members 18. o

The-mounting rings 11 and 12 of the fan 10 are rovided with flanges 24 and 25 which when tted together space the rings 11 and 12 apart a distance equal to the thickness of the mounting plates 21 and 22, so that when those rings are slipped onto opposite sides of the mounting plate and the screw bolts 26 and 27 are tightened, the fan is securely mounted to the mounting plate and in turn to the side rails 13 and 14 of the panel structure.

Sinceythe opening formed by the flanges 24 and 25 of the fan mounting rings spaces the rings 11 and 12 apart a distance equal to the thickness of thevmounting plates 21 and 22, that distance is greater than the thickness of the panel members 15 and 16 and I have therefore provideds'pacing strips 28 which are formed over the curved edge of the panels 15 and 16 Where those edges eX tend into the slot between the mounting P rings 11 and 12, these members 28 being of suilicient thickness to tightly clamp the panel between the rings 11 and 12.

The spacing members 17, 18 and 28 may be llfelt, soft rubber, or any other preferred material of rather soft nature, or if desired the inner spacer 17 which is in contact with the glass panels may be a soft material and the anel members 15 and 16 over the,

In assemblin anel structure in accordance with t e teac ings of my invention,

the side rails 13 and 14 are cut to length, the mounting plates 21 and 22 are pressed into these rails and riveted therein. The rails are then plated and polished, or finished in any other preferred manner, and the panel structure is subsequently finished by pressin the rails on over the panel members 15 an 16 to hold them in planar relation with their recessed ends abuttlng against opposite sides of the mountingv plates 21 and 22. It will be noted that no end strips are placed on over the panel members 15 and 16 slnce those ends lie within the channels 2 and 3 of the mounting bracket 1 and behind the planar section of that bracket when the panel is installed in a Window. p

The indentures in the adjacent ends of the panel members 15 and 16 and the inner ends of the mounting plates 21 and 22 all fall on the circumference of a circle, and the fan 10 is mounted in this circle by ring members 11 and 12 in the obvious manner.

The unit so constructed is graceful in its appearance and solid in its construction, and since the metallic side rails are narrow, the panel so constructed obstructs a minimum amount of the window opening so that the entrance of light into the room through that opening is practically unhampered by the installation of the Ventilating panel.

While I have chosen to show my invention by illustrating a preferred embodiment of it, I have done so by way of example only as there are many modifications and adaptations which can be made by one skilled in the art without departing from the teachings of my invention.
